The Universe is big, as Douglas Adams would say. The most distant light we can see is the cosmic microwave background (CMB), which has taken more than 13 billion years to reach us. This marks the edge ...

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story ...

A new JCAP study tests an “emulator” to reconstruct the large-scale structure of the cosmos If you think a galaxy is big, compare it to the size of the Universe: it’s just a tiny dot which, together ...

What if the Universe were not symmetrical? This idea, which goes against what scientists have long believed, emerges from new studies on large cosmic structures. Instead of being uniform in ...

Velocity streamlines within the reconstructed volume, with colored envelopes associated with the prominent nearby basins of attraction. The map and streamlines have been cropped to the region covered ...

Hubble tension reveals discrepancies in cosmic expansion rates, leading to investigations of rotating universes and their ...

In the grand puzzle of the cosmos, one question continues to defy easy answers: how fast is the universe expanding? Astronomers have tried two main methods to figure it out, but their numbers don’t ...

Astronomers have known for decades that the universe is expanding. When they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from Earth. To astronomers, the ...

Subir Sarkar receives funding from the UK Research & Innovation (UKRI) councils. The shape of the universe is not something we often think about. But my colleagues and I have published a new study ...

There are dark places out there in the deep universe, vast Saharas hundreds of millions of light years across, empty except for a stray hydrogen atom or a bit of radiation. They are the cosmic voids, ...
